Title: Semiconductor device
Inventor: KOBIKI MICHIHIRO
IPC: H01L29/812
Filed: 1985-01-25
Abstract: PURPOSE:To increase gains at high frequency by forming a through-hole electrically connecting an insular source electrode to a back electrode formed onto the second main surface of a semiconductor device. CONSTITUTION:A FET1 constituted by through-holes 10 shaped to a semi- insulating substrate 2 in order to electrically connect an insular source electrode 4 and the second main surface of the FET1, a back electrode 11 and a bridge electrode 12 is soldered (die-bonded) to carriers, thus grounding the source electrode 4. Consequently, source inductance and source resistance can be reduced, and high gains can be obtained when the device is used for a high-frequency amplifier. Even when die bonding is insufficient and thermal or electrical dispersion is generated in a chip, the dispersion can be relaxed by the bridge electrode 12, thus acquiring high reliability.

Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To prevent malfunctions by external noise by providing a mechanical reverse rotation prevention device between an electric motor rotary shaft and a feed screw. SOLUTION: A small gear 7 is fixed to the rotary shaft of an electric motor 6 and is engaged with a large gear 8 mounted to the feed screw 5 through a unidirectional clutch 9. A parallelly movably provided slider 3 engaged with the feed screw 5 is engaged with the end part of a sucker 2. By the constitution, when the electric motor 6 is driven in a prescribed direction, the unidirectional clutch 9 is operated in a transmission direction, the feed screw 5 is rotated and the slider 3 is operated so as to make the sucker 2 push transfusion in a discharging direction. However, when the driving electric motor 6 is reversely rotated by the cause of some external noise, the unidirectional clutch 9 is slid and rotation is not transmitted to the feed screw 5. Thus, the reverse movement of the sucker 2 by the slider 3 is not present.  In such a manner, the malfunction by the external noise is prevented.
